| 00:09 | types of fractions REVIEW . Hello , Children today let | |
| 00:16 | us revise fractions . A fraction is a part of | |
| 00:24 | a whole . It represents one or more equal parts | |
| 00:29 | of a whole object . Look at the Fraction 3/4 | |
| 00:36 | . The number above the line is the numerator . | |
| 00:40 | It indicates the number of equal parts considered . The | |
| 00:45 | line is called Fraction bar or division bar . The | |
| 00:50 | number below the fraction bar is called the denominator . | |
| 00:56 | It indicates the total number of equal parts the whole | |
| 01:00 | is divided into kids . A fraction is also a | |
| 01:07 | part of a set . Look at an example . | |
| 01:12 | Take a set of four bottles . Three are red | |
| 01:16 | and one is green . Here , we say , | |
| 01:20 | 3/4 of the bottles are red . When two or | |
| 01:24 | more fractions are given , depending on the value of | |
| 01:28 | their denominators , they can be termed as like or | |
| 01:33 | unlike fractions like fractions . Fractions with the same denominators | |
| 01:40 | are called like fractions , for example , one upon | |
| 01:46 | four , three upon four et cetera . Unlike fractions | |
| 01:53 | , fractions with different denominators are called unlike fractions , | |
| 01:58 | for example , five upon 85 upon three , two | |
| 02:04 | upon seven et cetera . Now let us revise the | |
| 02:09 | types of fractions one proper fractions , a fraction in | |
| 02:16 | which the numerator is less than the denominator is called | |
| 02:21 | a proper fraction . For example , two is less | |
| 02:26 | than eight . Thus , we say that to eighth | |
| 02:32 | is a proper fraction . Two improper fractions , a | |
| 02:37 | fraction in which the numerator is greater than or equal | |
| 02:42 | to the denominator is called an improper fraction . For | |
| 02:46 | example , E five is greater than two . Thus | |
| 02:53 | , we see that five upon two is an improper | |
| 02:58 | fraction . B four is equal to four . Thus | |
| 03:05 | , we see that 4/4 is an improper fraction . | |
| 03:11 | Three mixed fractions , a mixed number also called as | |
| 03:17 | mixed fraction is the sum of a natural number and | |
| 03:21 | a proper fraction . Look at the three circles . | |
| 03:26 | The 1st and 2nd circles are completely colored , and | |
| 03:30 | half of the third circle is colored . When added | |
| 03:34 | . Together , we get 2.5 . This 2.5 represents | |
| 03:40 | a mixed number here . Number two is the natural | |
| 03:45 | number , and half is the fraction . Now let | |
| 03:50 | us change a mixed number to an improper fraction . | |
| 03:55 | Convert five and three upon nine into an improper fraction | |
| 04:01 | . To do this , multiply the natural number by | |
| 04:05 | the denominator and then add the numerator to the product | |
| 04:11 | to get the new numerator right . The denominator as | |
| 04:15 | it is therefore five and three upon nine is equal | |
| 04:23 | to five into nine in brackets plus three upon nine | |
| 04:29 | , which is equal to 45 plus three upon nine | |
| 04:33 | that is equal to 48 upon nine . Thus , | |
| 04:38 | five and three upon nine is equal to 48 upon | |
| 04:44 | nine . Next , we will change an improper fraction | |
| 04:50 | into a mixed number . Look at the given fraction | |
| 04:54 | to convert into a mixed number . We divide the | |
| 04:58 | numerator nine by the denominator to we get the cautioned | |
| 05:04 | as four and the remainder as one . We write | |
| 05:09 | the mixed number as cautioned , plus remainder upon divisor | |
| 05:15 | . Thus , nine upon two is equal to four | |
| 05:19 | plus one upon to which is equal to 4.5 Children | |
| 05:27 | . Wasn't revising fractions fun . |
